RECIPROGATING DIE.

Specification of Letters Patent.

Patented-July 5, 1910.

Application filed January 16, 1906. gerlal No. 298,413;

To all whom it may concern Be 'it known .that I, FREDERICK RICHARD- SON, acitizen of the United States,'residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Reciprocating Dies, of which the/following is a specification.

This invention has reference to an im-' o provement in reciprocating dies adapted to cut and crimp a double tip in the process of manufacturing shoe 'or similar lacings.

The object of my invention is to facilitate the manufacture of my improved lacing tip, reference being had to Letters Patent of the United States 722,902, issued tome March 17, 1903, for an improvement in lacing tips. A. further object of my invention is to automatically release the tips from the die after the die has cut and crimped the tips. My invention consists in the peculiar and novel construction of a reciprocating die comprising a fixed member and a reciproeating member, each member having a series 25. of interlocking blades adapted to first cut a double tip centrally forming two tips, then crimp bo'th tips, and-then releasethe tips from the die in one operation of the die, as

- will be niore fully set forth hereinafter.

Figure 1 is a vertical side view of. my improved reciprocating die, showing the die in the open position. Fig. 2 is a vertical sectional view taken on line 2 2 of Fig. 1, looking at the front of the die and showing Fig. 3 is a Fig. 2, showing the die in the closed position. Fig. 4 is a transverse sectional view taken on line 4 4 of Fig. 1. Fig. 5 is a 510 transverse sectional View taken on line 5 5 of F ig. 1, showing the means of securing the blades in the die. Fig. 6 is a detail view looking at the side of one series of crimping blades removed from the die and show- I ing the same in the position they would assume with the die in the open position.

Fig. 9 is a side view of the cutting blades and the end forming blades removed from 1 the die, showing the same in the position they would assume with the die in the open position. Fig. 10 is a side view similar to blades'in the position the would assume with the die in the close position. Fig.

Figs. 13, 14 and 15 areenlarged detail views illustrating the operation of my improved die on a double lacing tip.

In the drawings,a indicates the fixed member, b the reciprocating member, 0 0 the crimping blades in the fixedand the recip rocating members, co the cutting blades, f f the end-forming blades, 9 g, the fastening bolts, 11. the lower anvil, and i the upper anvii for the cutting blades of my improved reciprocating die.

, The fixed member a consists of a base a havingthe hole a and-the o ening a for securing the member in, the ie press, the two upwardly-extending sides a a in which are the edge openings a a through which a lacing with adouble tip, 'as shown in Fig. 13, is inserted in the die, and the transverse holes a 11 adjacent the base for a fastening bolt g. A front plate composed of the two overlapping parts a and a is secured to the front edge of the'sides a a by the screws or a through slots in the plates which allow for side adjustment of the lates, and this side adjustment is controlled by the screws a a which extend inward from the edge of the plate or part a and engage with the plate or part a", asshown in Fig. 5. These plates have the central adjacent inner edges a a spaced to receive the front edges of the cutting blades e c, asshown in Fig. 4,

and the lower cut-away portion a for the anvil 72., as shown in .Fig. 5. A back plate composed of the two overlapping parts a and a is secured to the .rear edge of the sides a a5 by the screws a a through slots in the plates which allow for side adjustment of the parts and this side adjustment is controlled by the screws a" a which extend inward from the' edge of the part a and engage with the part a, as shown in Fig. 5. These parts have the central adjacent inner-edgesiz a spaced to receive the rear edges of the cutting blades e. e.
